Abstract
A structure, and more specifically a tube-shaped structure having an inner surface and two ends, wherein one or both ends are open and the inner surface is exposed through said one or both open ends, and a metal provide on the inner surface. Also, an electrode active material, such as lithium metal, on the metal included on the inner surface of the tube.
Claims16
A structure comprising:
- a tube having an inner surface forming a cavity and two ends, wherein one or both ends are open;
- a metal on the inner surface of the tube;
- and
- lithium metal formed on the metal,
- wherein the metal included on the inner surface of the tube is one or more selected from the group consisting of Au, Zn, Ag, Al, Pt, In, Co, Ni, and Mn,
- wherein the tube has an inner diameter of 0.1 μm to 1.8 μm, an outer diameter or 0.2 μm to 2 μm, and a length of 2 μm to 25 μm, and
- wherein the tube has an aspect ratio (a) of a longitudinal section calculated by Equation 1;
- and
- wherein the aspect ratio (a) is more than 1:
- a=L/Dex [Equation 1]
- in Equation 1, L is the length of the tube and Dex is the outer diameter of the tube.
